EXAMINE THE EFFICIENCY OF THE DUAL COAGULANT FERRIC ZINC CHLORIDE (FZC) FOR REMOVAL OF THE ORGANIC SUBSTANCE FROM LANDFILL LEACHATE

Features and discharge standard, pollution issues, and environmental concerns are outlined in this study, and commonly used remedies for municipal solid waste dumps. FTIR spectroscopy and a Zetasizer were used to identify the properties of ferric chloride. The jar test was used to determine the influence of pH and ferric chloride dose on leachate. It was determined that pH 6 and 3600 mg/L of ferric chloride were the sweet spots. Maximum sludge density and quickest settling speed were achieved at the optimum pH and dosage; the SVI value was 81.2 mg/L, which is considered adequate at a settling speed of 0.5728 cm/min. One of the metal salts, ferric chloride, may effectively lessen the need for both colour and chemical oxygen.
